ROTARY NOZZLEHHEAD FOR WATER-MOTORS.

SPECIFICATION forming part of Letters Patent No. 380.691, dated April10, 1888.

Application filed December 22, 1886. Serial No. 222,245. (No model.)

To all whom it may concern:

Be it known that I, EDWIN S. PIPER, residing at Bristol, in the countyof Hartford and State of Connecticut, have invented certain new anduseful Improvements in Rotary Nozzie-Heads for WatenMotors; and I dodeclare the following to be a full, clear, and exact description of thesame, reference being had to the accompanying drawings, which form apart of this specification.

My invention relates to an improvement in nozzle-heads for water-motors,the object being to produce a head carrying several nozzles, each ofdifferent size, adapted to relieve the rotating nozzle-frame from thepressure of the water and to compensate for wear, and combiningsimplicity and cheapness of construction with durability and generaleft'lciency in use.

With these ends in view my invention consists in a nozzle-head .havingcertain details of construction and combinations of parts, as will behereinafter described, and pointed out in the claim.

In the accompanying drawings, Figure l is a view in perspective of anozzle-head em bodying my invention, together with a portion of awater-wheel. Fig. 2 is a view of the head in front elevation, and Fig. 3is a view of it in central longitudinal section.

As herein shown, the forward end of the water'supply pipe A is providedwith a bearing consisting of a frustoconical cap, B, having :itstapering face or side and flat end ground to form a bearing-surface, andprovided in its tapering face and upon its under side with adischarge-port, C, of forward pitch.

The frame D is provided with a circularl series of wings, E, inclinedoutwardly from its rear to its forward end, and respectively havinginclined water-passages F, conforming in inclination to the pitch of thedischarge-port, with which their inner ends are brought into alignmentby the rotation of the frame.

Nozzles G, each of different size, are located in the respective wingsand form extensions of their water-passages. A central opening orrecess, H, extending forward into the frame from the rear face thereof,adapts it to fit over the bearing or cap upon which it rotates, the

walls of such opening or recess being ground to form a close jointbetween the two surfaces.

A pivot, I, located in the center of the frame and entering the centerof the flat end 'of the cap, secures the frame to the said cap. All wearbetween such frame and cap is compensated for by readjusting the saidpivot, which consists of a screw left unthreaded where pass ing throughthe frame.

The rear edge of the frame is provided with a slot, J, for and locatedin line with each wing, such slots receiving a spring-actuated pawl, K,pivoted to the cap and holding the frame in its several positions ofadjustment upon the bearing.

A yoke, L, secured to the forward end of the frame, carries a spindle,M, having an operatingwheel, N, by which the frame is rotated, securedto its outer end. Y

The described head is located close to the water-wheel O, which receivesthe water direct from the nozzles.

In using my improvement the frame is rotated to bring the waterpassageof a large or small nozzle into alignment with the dischargeport,according to the power required and to, the pressure or head of thewater. In this way the amount ot'water consumed is made to depend uponthe power required with obvious economy.

Under my invention the frame is relieved of the pressure of the water,wear is reduced to the minimum, and leakage avoided. Fur- Vthermore,without breaking the water, it gives it advantageous direction upon thewheel.

I would have it understood that I do not limit myself to the exactconstruction and combination ot' parts herein shown and described, buthold myself at liberty to make such changes and alterations as fairlyfall within the spirit and scope of my invention.

I am aware that a nozzle -head having a frame carrying a series ofparallel cylindrical nozzles each of different discharging capacity andadapted to be rotated to bring them into alignment with a singleaperture communicating with a water-supply is not new. I am also awarethat a head having a series of cylindrical tangential waterpassages anda discharge-port for each is not new, and that it IOO is old tocentrally pivot a conical cap having discharge-openings. I do not,therefore, broadly claim any of these constructions, but only theparticular construction shown and described herein.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In a nozzle-head for water-motors, the combination, with a hollowconical bearing having its larger end open and adapted to be secured toa water-supply pipe, its smaller end closed to form a ilat bearing-face,and a discharge-port of forward pitch in its side, of a rotary frameconed out to t over such conical bearing and the iiat face thereof andad.-
